observational
2026
PURPOSE: To evaluate whether the outcomes and characteristics of a first IVF/ICSI cycle are associated with embryological and clinical outcomes in a subsequent cycle performed within 2 years. METHODS: This retrospective single-center obser…
observational
2026
PURPOSE: To evaluate whether artificial endometrial preparation using hormone replacement therapy (HRT) influences clinical and neonatal outcomes compared with modified natural cycles (mNC) in single euploid vitrified-warmed blastocyst tran…

STUDY QUESTION: Does germinal vesicle (GV) rescue by IVM provide a meaningful clinical benefit in patients with unexpectedly low mature oocyte yield, and which patient profiles are most likely to benefit? SUMMARY ANSWER: Especially in pati…
observational
2026
PURPOSE: To identify treatment-related factors influencing low oocyte maturation rates in standard ovarian stimulation (OS) cycles and patients' candidates for clinical studies on rescue-IVM. METHODS: Retrospective study including retrieva…
observational
2026
AIMS: To evaluate DuoStim strategy across a decade from its clinical implementation in IVF by comparing embryological and clinical outcomes between the first and second ovarian stimulations (1st-OS and 2nd-OS) conducted within 30 days, focu…

STUDY QUESTION: What updates of the International Glossary on Infertility and Fertility Care are required, to reflect contemporary scientific knowledge, social needs, and inclusive definitions, while harmonizing international communication …
observational
2025
PURPOSE: This study is to evaluate the effectiveness of a PPOS protocol in poor prognosis patients undergoing IVF with DuoStim and PGT-A versus the conventional protocol with GnRH antagonist. METHODS: Retrospective cohort study encompassin…
observational
2025
PURPOSE: To evaluate the performance of different embryo transfer (ET) operators in a strictly controlled scenario minimizing potential confounders. METHODS: This single-center retrospective cohort study analyzed vitrified-warmed single eu…
observational
2025
PURPOSE: The time at which embryo developmental velocity variations occur remains unknown. Therefore, we analysed the morphokinetic trajectory of human early fertilisation from the extrusion of the second polar body (PB2) to pronuclear brea…
observational
2023
PURPOSE: To investigate whether high relative humidity conditions (HC), when using a time-lapse system (TLS) with sequential culture media, are beneficial to embryo culture, improving ongoing pregnancy rates. METHODS: We included patients …
observational
2023
PURPOSE: An impact of different gonadotrophins selection for ovarian stimulation (OS) on oocyte competence has yet to be defined. In this study, we asked whether an association exists between OS protocol and euploid blastocyst rate (EBR) pe…

2020
CAPSULE: This expert opinion summarizes current knowledge on risk factors for infertility and identifies a practical clinical and diagnostic approach for the male and female partners of an infertile couple aimed to improve the investigation…

PURPOSE: To detect putative differences in the miRNomic profile of follicular fluids collected after follicular-phase-stimulation (FPS-FFs) and paired luteal-phase-stimulation (LPS-FFs) in the same ovarian cycles (DuoStim). METHODS: Explor…

2019
PURPOSE: To investigate the association of cumulus cell (CC)-related expression of a selected cluster of key genes (PTGS2, CAMK1D, HAS2, STC1, and EFNB2) with embryo development to blastocyst. METHODS: Exploratory study at a private clinic…
observational
2019
This multicenter study evaluated the reliability of the recently published ART calculator for predicting the minimum number of metaphase II (MII) oocytes (MIImin) to obtain at least one euploid blastocyst in patients undergoing in vitro fer…

2016
BACKGROUND: Preimplantation genetic screening (PGS) provides an opportunity to eliminate a potential implantation failure due to aneuploidy in infertile couples. Some studies clearly show that twins following single embryo transfer (SET) ca…

STUDY QUESTION: What is the optimal stage from oocyte through preimplantation embryo development for biopsy and preimplantation genetic screening (PGS) to detect abnormal chromosome segregation patterns in eggs or embryos from advanced mate…
